Eye, by the Adion of the Fibres of the whole 

 Eye-lid, which parting from its Origin, proceed 

 to join themfelves to its Tiarjus, 



To extend this Eye-lid over the Ccrnea., there 

 were two Mufcles that were feen, when fix were 

 taken away, which ferv'd to the Motion of the 

 whole Eye ; we found that the greateft of thefe 

 tw^ Mufcles has its Origin at the very edge of the 

 great Circle of the Sclerotica^ towards the great 

 Corner, from whence the Eye-lid takes its Ori- 

 ginal ; it is very flefhy in its beginning, which is 

 a large Bajis, from whence coming infenfibly to 

 contrail itfelf by paffing under the Globe of the 

 Eye, like as the Eye-lid paffes over it, it ap- 

 proaches the Optick Nerve, where it produces a 

 Tendon round and (lender, fo that it paffes thro' 

 the Tendon of the other Mufcle, which ferves for 

 a Pulley, and which hinders it from preffing the 

 Optick Nerve, upon which it is bent, and makes 

 an Angle, to pafs thro' it to the upper Part of the 

 Eye, and coming out from underneath the Eye 

 to infert itfelf at the Corner of the Membrane 

 which makes the internal Eye-lid; this fecond 

 Mufcle hath its Original at the fame Circle of 

 the Sclerotica^ but oppofite to the firft towards 

 the little Corner of the Eye, and paffmg under 

 the Eye like the other, goes to meet it, and em- 

 braces its Tendon, as has been declar'd. 



The Aftion of thefe two Mufcles is, in refped 

 to the firft, to draw, by the means of its Cord or 



Z 3 Tendon,
